WTB: Cat for MY04 2.5i + rear coilovers (Melbourne)

[circlethesky]

Seems like my cats blocked so I need a new one, hoping to get one this weekend but thought I would try here before I go to the wreckers.

I've also got a really creaky coilover. The sound has always been there but lately it has become unbearable so if anyone has had the same problem and has the rears that are still good (or a single rear kido) that I could have cheap let me know!
